But it turned out to be difficult to attack Adelson without invoking problematic stereotypes, or claiming that Adelson's "Macau casino money" was all bad, considering he also donates generously to important projects like Birthright Israel (Just today, the Adelson family pledged an additional 13 million dollars to reduce the waiting list, on top of the 20 million dollar pledge he made earlier this year). The National Jewish Democratic Council even had to scrap its petition against Adelson's "tainted money."

But Jewish Democrats won't let up, and a new attack dog has been let loose on the casino billionaire. This time it's a Chihuahua, accompanied by the Jewish comedienne with the biggest mouth around. In 2008, her "Big Schlep" video calling on Jewish youths to convince their grandparents to vote for Obama went viral - and even prompted Jackie Mason's Jewish Republican response, calling her a "yenta."

This time, it's all about Adelson, or just Sheldon, as Silverman prefers to call him.

"Billionaires are giving Romney a record-breaking amount of money for his campaign this year", the video says. "Seventy-eight-year-old casino magnate Sheldon Adelson of Las Vegas has pledged to give Romney 100 million dollars to defeat Barack Obama. Sarah Silverman has a proposition for you, Sheldon."

Looking straight down the barrel of the camera, Silverman presents her "indecent proposal" to Adelson.

"If you give that 100 million dollars to Obama instead of Romney, I will…" she starts, "well, I won't have sex with you, because we are not married and I am a nice girl. But I will scissor you wearing a bikini bottom through to fruition. That means until you (beep)."

"Do you know how many Republican billionaires are giving money to Romney? All of them! How many of them are getting scissored by a bikini-bottom wearing Jewess with big naturals? How many? How many, Sheldon? You'll be the only elderly billionaire on the planet to have traditional lesbian sex through to climax with a girl who had her own show on Comedy Central. I mean, talking about bragging rights, that's…"

Then Silverman, lying on a couch and indeed wearing a bikini, briefly tries to demonstrate on a Chihuahua dog what she intends to do to Adelson.

The U.S. comedienne then urges the public to visit a website where they can sign a petition to "to help cut Mitt Romney free from his sugar daddy." The website lists several facts about the big donor, including his wealth estimate, his remarks on influencing the elections, his first choice of candidate (Newt Gingrich) and his positions on the Palestinian-Israeli conflict ("He thinks that the Palestinians are an invented people and hates on AIPAC for being too pro-Palestinian").

Some people will probably find the video vulgar - but that won't prevent it from receiving numerous clicks.

In a very different arena, an attempt to curb the influence of so-called Super PACs on the elections process has failed today: the U.S. Senate has blocked the Disclose Act - legislation meant to force independent groups supporting one of the political candidates to disclose the names of $10,000 plus donors. The Republicans opposed the measure, claiming it would discourage donors.

U.S. President Barack Obama said in a statement that he is disappointed with the inaction of the Republican Senators. "Two years ago, the Supreme Court ruled in Citizens United that big corporations are allowed to spend unlimited amounts of money to influence American elections. They can buy millions of dollars worth of TV ads with no obligation to reveal who’s actually paying for them," said Obama. "The consequences of this decision are predictable. If we allow this practice to continue, special interests will have unprecedented influence over politicians. It’s wrong. It’s corrosive to our democracy, and it’s a threat to our future."

National Council of Jewish Women CEO Nancy Kaufman said in a statement: “The failure of the Senate to muster the 60 votes needed to end a filibuster and make way for debate on the DISCLOSE Act, a bill that would require disclosure of the names of political contributors, including corporations, and the amounts they give to each campaign, is a major setback for our democracy. Today’s defeat of this bill is a sad commentary on the collapse of the post-Watergate consensus that anonymous cash in elections is a dangerous thing."
